Abstract

Dual polarisation antenna having low side lobes, useful in a satellite radiocommunication system. The antenna comprises a reflector assembly (12) illuminated by a feed source (11), and the reflector assembly (12) comprises a front reflector (15) that reflects two electromagnetic waves orthogonally polarised and each at a different frequency, an auxiliary reflector (16) that reflects one of the orthogonally polarised electromagnetic waves, and a deflecting surface (13) that totally diffracts the orthogonally polarised electromagnetic wave that passes through the auxiliary reflector (16). <IMAGE>
